Covestro Makrolon Polycarbonate Sheets are considered unbreakable
Makrolon Polycarbonate materials have a balance of useful features this includes temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastic materials and engineering materials.
Polycarbonate is definitely a tough material. Although it has extraordinary impact-resistance, it has a lower scratch-resistance and so a hard coating can be applied to polycarbonate eye wear and polycarbonate exterior vehicle equipment. The characteristics relating to polycarbonate are along the lines of those of common Acrylic materials, although polycarbonate is always stronger, it is usable in a wider temperature range and is a bit more expensive. This plastic polymer is highly transparent to visible light and it has better light transmission characteristics than several types of glass.
Polycarbonate has a glass transition temperature of around 150 °C (302 °F), therefore it softens slowly above this point and flows above about 300°C (572 °F). Tools should be held at warm to high temperatures, generally above 80 °C (176 °F) in order to make strain- and reduced stress products.
Unlike most thermoplastics, polycarbonate can undergo dramatic shape changes without breaking. For that reason, it is sometimes processed and formed without needing to be heated using standard sheet metal techniques, which include forming bends on a brake. For even sharp angle bends having a tight radius, no heating is usually necessary. This makes it valuable in prototyping applications where transparent or electrically non-conductive parts are necessary, which can't be produced from sheet metal. Please keep in mind PMMA/Plexiglas, which is similar in appearance to polycarbonate, but it's brittle and can't be bent without heating.
The light weight of polycarbonate, compared with glass, has led to growth and development of electronic touch screens that replace glass with polycarbonate, for use in mobile and portable devices. Such displays include newer e-ink and many LCD screens, though CRT, plasma screen and other LCD technologies generally still require glass for its higher melting temperature and the ability to be etched with finer detail.
Other kinds of items manufactured from Polycarbonate include durable, lightweight luggage, MP3/digital audio player cases, computer cases, police riot shields, instrument panels, and blender jars. Many toys and hobby items are manufactured from polycarbonate parts, e.g. fins, gyro mounts, and flybar locks for use with radio-controlled helicopters.
For use in applications exposed to weathering or UV-radiation, a special surface treatment is needed. This can be a coating (e.g. for improved abrasion resistance), or perhaps the coextrusion for enhanced weathering resistance.
Bayer Makrolon Polycarbonate is a thermoplastic that starts as a solid material in the form of small pellets. In a manufacturing process called injection molding, these small pellets are heated until they melt and become a very thick liquid. This liquid polycarbonate is then rapidly pushed into a mold with the empty part being the size and shape of the part you want, compressed under high pressure and cooled to produce a finished product , all in just a minute or so.
